《高考英语学科复习关键问题指导与训练》-阅读理解中的问题突破与指导

2022届高三考英语学科复习关键问题指导与训练》第三次选送——阅读理解中的问题突破与指导阅读理解在新高考英语试卷中，赋予了较多的内容和较高的分值，主要考查学生能否正确理解阅读文本并从文本中找到解决问题答案的能力，对学生英语学科素养要求较高，是高中英语的教学与复习的重点与难点。目前，在高三复习阶段教学和测试中，学生在阅读理解中语篇整体意义、逻辑关系和内在连贯等综合阅读能力方面把握不足，寻找关键词能力较差，联系前后句、根据上下文意思把握不准，即使找到信息也无法较好地对信息进行概括、整合与分析。语篇中长难句依然是学生阅读理解过程中最大的障碍。在高考中考生在阅读理解中D篇得分率较低，失分尤其突出。为了使阅读方面的复习更有针对性，有效解决阅读中学生的问题，寻找进一步的突破，我们组织了中国教育学会普通高中新课程实施“领航计划”福建省高中教师新高考适应能力提升培训班的老师制作54个了“阅读中关键问题的突破和指导”的课件，我们再推出18位老师的课件，供大家参考使用。同时，我们也推出各设区市近年来选送的30篇阅读D篇供学生训练以及2022届高三毕业班诊断性测试的部分地市的学生习作供参考使用。(一)Sometimes,thesimplestideasarethebest.Forexample,toabsorbheatfromthesuntoheatwater,youneedlarge,flat,blacksurfaces.Onewaytodothatistobuildthosesurfacesspecially,ontheroofsofbuildings.Butwhygotoallthattroublewhencitiesarefullofblacksurfacesalready,intheformofasphalt(柏油)roads?Tenyearsago,thisthoughtcameintothemindofAriandeBondt,aDutchengineer.Hefinallypersuadedhisbosstofollowitup.Theresultisthattheirbuildingisnowheatedinwinterandcooledinsummerbyasystemthatreliesonthesurfaceoftheroadoutside.Theheat-collectorisasystemofconnectedwaterpipes.Mostofthemrunfromonesideofthestreettotheother,justundertheasphaltroad.Some,however,divedeepintotheground.Whenthestreetsurfacegetshotinsummer,waterpumpedthroughthepipespicksupthisheatandtakesitundergroundthroughoneofthedivingpipes.Atadepthof100metresliesanaturalaquifer(蓄水层)intowhichseveralheatexchangers(交换器)havebeenbuilt.Thehotwaterfromthestreetrunsthroughtheseexchangers,warmingtheground-water,beforereturningtothesurfacethroughanotherpipe.Theaquiferisthususedasaheatstore.Inwinter,theworkingsystemischangedslightly.Waterispumpedthroughtheheatexchangerstopickuptheheatstoredduringsummer.Thiswatergoesintothebuildingandisusedtowarmtheplaceup.Afterperformingthattask,itispumpedundertheasphaltanditsremainingheatkeepstheroadfreeofsnowandice.1.Whichofthefollowingistrueaccordingtothefirsttwoparagraphs?A.AriandeBondtgothisideafromhisboss.B.Large,flat,blacksurfacesneedtobebuiltincities.C.TheDutchengineer’ssystemhasbeenwidelyused.D.Heatcanalsobecollectedfromasphaltroads.2.Forwhatpurposearethedivingpipesused?A.Toabsorbheatfromthesun.B.Tostoreheatforfutureuse.C.Toturnsolarenergyintoheatenergy.
